A Function Algebra Providing New Mergelyan Type Theorems in Several Complex Variables

[OWP-2019-02] Falcó, Javier; Gauthier, Paul Montpetit; Manolaki, Myrto; Nestoridis, Vassili (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-11)

For compact sets $K\subset \mathbb C^{d}$ , we introduce a subalgebra $A_{D}(K)$ of $A(K)$ , which allows us to obtain Mergelyan type theorems for products of planar compact sets as well as for graphs of functions.
Groups with Spanier-Whitehead Duality

[OWP-2019-23] Nishikawa, Shintaro; Proietti, Valerio (Mathematisches Forschungsinstitut Oberwolfach, 2019-09-17)

We introduce the notion of Spanier-Whitehead $K$ -duality for a discrete group $G$ , defined as duality in the KK-category between two $C*$ -algebras which are naturally attached to the group, namely the reduced group ...
